Title: A device for feeding the film in roll film photographic cameras
IPC: G03B19/04
Filed: 1956-03-02
Abstract: 822,026. Photographic cameras. MEOPTA-PREROV, NARODNI PODNIK. March 2, 1956 [March 2, 1955], No. 6576/56. Class 98(1) In a roll-film camera, the film is automatically arrested after the advance of the required length by means of a filmdriven member of an exposure counter breaking the lock by which one lever holds another out of engagement with a ratchet connected with the film wind. As shown, gear wheel 4 meshes with wheel 3 fast with roller 1 which is driven by the film and the required length is advanced during one complete revolution of wheel 4. Striker 6 carried by wheel. 4 co-acts with arm 9a of lever 9 and lifts arm 9b so that pin 16 slips underneath the dog 13b, engages ratchet 17 and stops the film wind (Fig. 5). Lever 30 is turned clockwise about pivot 31 against tension spring 32 by the shutter release mechanism and acts on lever 13 through rod 37 to free the film wind by turning lever 13 clockwise about pivot 14 against tension spring 36 thus allowing lever 9 to return under tension spring 10 to stop 12 before the shutter opens. The lost-motion between lever 30 and collar 40 'prevents lever 34 from trapping lever 30 and, during the clockwise motion, inclined surface 41 engages abutment 42. On return of lever 30 to stop 33 after exposure, lever 34 interlocks therewith under tension spring 36 to prevent a further operation of the shutter before the film is changed. The interlock is released, on completing the film change, by tension spring 15 turning levers 13 and 34 anti-clockwise about their pivots against tension spring 36 (Fig. 5). On changing the last frame the mutilated portion of indicator disc 19 of the exposure counter is brought opposite strike 6 so that the counter is no longer operated thereby and pin 23 on disc 19 holds arm 13d of lever 13 so that the film wind remains free and the trailing end may be wound off. When the camera body is opened lever 24 having arm 24c co-operating with an operable wall (Fig. 4, not shown), is rotated anti-clockwise by tension spring 26. Pawl 27 is thus moved from holding counter disc 19 and arm 24a retains arm 13d so that disc 19 may, under spiral spring 21, carry pin 23 back to the zero position in which pin 23 abuts stop 12 (Fig. 3). On winding on the leading end of an unexposed film striker 6 is rotated to arm 24b and thereafter the film slides over stationary roller 1 and is wound until marks on the backing paper come opposite marks provided on the camera body. The wall is then closed, removing arm 24a from pin 16, bringing pawl 27 into engagement with disc 19 and freeing striker 6, arm 13d of lever 13 being retained by cam 22 of disc 19 (Fig. 4, not shown). On continued winding of the film, striker 6 rotates exposure disc 19 and at the revolution of wheel 4 immediately preceding the positioning of the first frame in the exposure aperture, cam 22 moves from arm 13d so that the latter is finally held by, arm 9. The preferred camera is a twin lens reflex. Specifications 426,915, 431,982, 495,276 and 646.721 are referred to

Title: Improvements in or relating to processes for the production of shaped carbon articles
IPC: C04B35/52
Filed: 1956-03-07
Abstract: In the production of carbon articles, a shaped article is produced from a mixture of a carbon-containing substance, e.g. coal, coke, or semi-coke, and a carbonaceous binder, e.g. tar, pitch, or synthetic resin, the article is subjected to an initial heat treatment for several days at 100-250 DEG  C. to harden the binder by polymerization or condensation, and the initially-heated article is subjected to a subsequent final heat treatment to convert the article to amorphous carbon or graphite. Hardening of the binder may be facilitated by allowing access of air during the initial heating, when temperatures at the lower end of the range are used, or by including a polymerization accelerator in the binder, either admixed therewith or acting in gaseous form, e.g. chlorine, hydrogen chloride, polyvinyl chloride, chlorobenzenes, sulphur, sulphides, thiosulphates, thionyl chloride, aliphatic compounds, furfural, hydroquinone, naphthols, phenols, gallic acid, amino-, diamino-, and nitroso-compounds, cumolhydroperoxide, and benzoyl peroxide.  The initial heating, which may be for up to 20 days at 120-150 DEG  C., or, on average, 15 days at 150 DEG  C., or 10 days at 210 DEG  C., may be effected in an electrically, or superheated steam, heated chamber communicating, say through trap doors, with pre-heating and cooling chambers, through which the article passes in sequence, and the article may be embedded in powdered coke.  The initially-heated articles may be converted to amorphous carbon in an annular kiln at 1000-1300 DEG  C., or to graphite by direct passage of electric current in a graphitising furnace. Alternatively, the initial and final heating may be carried out continuously in an electrically, or gas heated tunnel kiln, the zone for initial heating being appropriately dimensioned in relation to the zone for final heating.

Title: Improvements in or relating to the production of viscous aqueous alkaline solutions of vegetable globulins
IPC: D01F4/00
Filed: 1945-03-23
Abstract: Viscous aged solutions obtained by dissolving undenatured vegetable globulins, for instance undenatured peanut globulins in dilute aqueous solutions of alkali metal hydroxides, adapted for extrusion in the manufacture of filamentary products are made by including in the aqueous alkali metal hydroxide solution of a vegetable globulin about 1/2 to 1 per cent of an alkali metal sulphite reckoned as anhydrous material on the weight of the water and permitting the thus treated solution to attain the desired viscosity.  The alkali metal sulphite may be introduced as such or as bisulphite and may be introduced into a previously formed solution of the vegetable globulin in aqueous alkali or may be present while the latter solution is being formed.  The viscosity of a matured solution thus made is less dependent on aeration during its preparation than a matured solution of comparable viscosity made without adding the alkali metal sulphite and is also less liable to surface gelation. In an example peanut globulin is wetted with part of the water taken to make up the sodium hydroxide solution and sodium sulphite is dissolved in the solution containing the sodium hydroxide and the remainder of the water the whole being then made into one solution. Maturing is carried out in a closed vessel and the resulting solution is suitable for the spinning of artificial filaments.  The Provisional Specification is not limited to aqueous alkali metal hydroxide solutions of undenatured vegetable globulins but refers generally to aqueous alkaline solutions of vegetable globulins. Specification 553,539 is referred to.
